Modifying DataGrid format

[Albert Valls Rovira]

Hello all...

I have a DataSet with two DataTables within
(for example...)

Table 1: Name Surnames CountryID
Table 2: id CountryName
I have created a relation between both tables (Table 1.CountryID - Table 2.id)

I create a DataGrid that shows the contains of Table 1, and rename, resize,
etc
In the DataGrid there is a cross allowing me to view the contains of Table
2, related to the selected register in Table 1 selected in the DataGrid.
But when I unfold the related tables I lose the format. I mean, I would like
to change the name of the columns, hide the Table 2.id column, etc.

Can this be done? How?

Many thanks!
